Abstract

The invention provides a control method and device of a single-pedal car, and the single-pedal car. The control method of the single-pedal car comprises the steps that the real-time working state of an accelerating pedal of the car is obtained; when the real-time working state expresses that the car is currently in a non-acceleration state with zero driving force, a first real-time speed of the car is obtained; and when the first real-time speed is smaller than a first preset value, an electronic stability program (ESP) of a car body of the car is controlled to brake a braking system of the car. According to the control method and device of the single-pedal car, and the single-pedal car, by obtaining the real-time working state of the accelerating pedal, when it is judged that the car is currently in a decelerating state according to the real-time working state and the real-time speed is smaller than the first preset value, the ESP is controlled to brake the braking system of the car,accordingly, the braking efficiency is improved, and the problem that a motor is low in braking force and efficiency at a low rotating speed is solved.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a control method and device for a single-pedal automobile and the single-pedal automobile. Background technique [0002] With the development of automobile technology, a single-pedal car with a single-pedal driving mode has appeared in the related technology. Its working principle is that after the accelerator pedal is released, the braking system will intervene and recover kinetic energy through the energy recovery system to achieve vehicle deceleration. and braking. [0003] However, due to the setting of the energy recovery system, manufacturers often make the braking time of single-pedal vehicles longer in order to recover the braking energy to a greater extent. Especially when the vehicle speed is low, because the braking force of the motor is small at this time, the braking time is long, the braking efficiency is low, and the driving experience is far inferior to that ...
